PirateKing:On domestic flights, why would you bother packing any toiletries? I mean, if they're special or prescription, I can see it.

But there's probably a national-chain grocery or drug store within 5 minutes of every major and most minor airports in the US.

You can buy a new tube of toothpaste.

You CAN do that. If you have a rental car and the willingness to take the time to do it. Not to mention, unless you're going to be there for a fair amount of time you'll end up throwing out what you don't use. That's a waste of money.
